Mitomycin, ifosfamide, and cisplatin in non-small cell lung cancer.

Mitomycin, ifosfamide, and cisplatin have demonstrated the best single-agent activity thus far in patients with non-small cell lung cancer (NSCLC), the most common malignant disease in the western world. For this reason, we initiated a phase II study, giving these three agents in combination (designated MIC) to 74 patients with inoperable NSCLC. Sixty-six patients were evaluable for response, of whom 30 (45%) demonstrated a partial response and 7 (11%) a complete response. These results, along with those obtained in two other phase II trials of MIC in NSCLC, promoted us to begin a large-scale, multicenter, phase III study of MIC in patients with inoperable limited-stage NSCLC. In this ongoing study, patients have been randomized to receive treatment with MIC and radiotherapy or radiotherapy alone. We hope to resolve the issue of whether a survival advantage is conferred on NSCLC patients treated with radiotherapy in combination with this promising chemotherapeutic regimen.
